3. Decision-making/limiting turnovers
To Henderson's credit, this area of improvement applies to practically every point guard entering their second NBA season, as point guards typically take longer to transition to the next level than other positions. Nonetheless, it's a key area that Scoot will need to improve in order to be the primary ballhandler and offensive initiator for the Blazers, especially if they decide to move off of Anfernee Simons and give Henderson and Shaedon Sharpe the keys to the franchise.
A team is only as good as its primary ballhandler, and Henderson is too reckless sometimes to be considered a reliable floor general. He did show encouraging signs of progressing as a playmaker towards the end of his rookie season, increasing his assists average from 4.7 to 7.1 per game following the All-Star break. But with those improved assist numbers also came more turnovers, going from 3.0 to 4.5 per game.
Henderson has excellent court vision and is a willing passer, but he must limit the risky and unnecessary passes he often made last season. However, his decision-making isn't only tied to his assist-to-turnover ratio; Henderson's inefficient shooting also had to do with his poor shot selection at times. To take that next leap, he needs to improve both in terms of maximizing (by limiting turnovers) and optimizing (through better shot selection) the Blazers' possessions.
